Nibi Metrics

Real-time water levels, forecasts, and alerts for lakes and rivers across Canada and the US. Built on official government data.

Nibi Metrics turns raw gauge readings from official hydrometric networks into something a person standing on a dock can actually use: is the water high or low for today, which way is it moving, and how unusual is this? This page explains where every number on the platform comes from and what we do to it along the way.

Water Stories

The flood of record that was overtaken

For five years, spring 2019 was the mark every Lake Muskoka decision answered to. In April 2026 the lake went two centimeters higher - and the official books have not caught up yet.

About Winter River at Union

Winter River - a lively stream nurturing its surroundings.

The Winter River meanders through the scenic landscape of Prince Edward Island, bringing life and vitality to the region. Positioned in the Central Prince Edward Island - Hillsborough watershed, this river serves as an important waterway in the area. With a drainage area of roughly 16.4 square kilometres above the gauge, the Winter River plays a role in the hydrological dynamics of its community, contributing to both local ecology and human activity.

The watershed context

Within this distinct watershed, the Winter River is joined by neighboring watercourses including Coles Creek at Miltonvale Pumping Station, West River at Riverdale, and Winter River near Suffolk. The hydrology of Prince Edward Island is characterized by a unique Atlantic pattern; rain and snowmelt drive the water levels, while groundwater-fed streams maintain steady baseflow. This combination supports the ecosystem along the Winter River, particularly during the short spring freshet experienced each year.

Why the data matters here

Monitoring the Winter River's flow is essential for understanding local water conditions. The gauge at Union tracks river data, providing insights into the seasonal rhythms and fluctuations of the watercourse. Today's reading, compared against the median for this calendar day from the Water Survey of Canada over the past 33 years, gives a clearer context than mere elevation alone. This information helps residents, visitors, and ecologists alike appreciate the changing conditions of the Winter River and their implications for the surrounding environment.

How this page is built

Readings come from official government gauges and are rolled into daily records: the daily mean, high and low for every day on record. Each calendar day gets its own baseline from the full history, so the level you see is compared against what this specific date usually looks like rather than an annual average.
